The dungeon air, already thick with the metallic tang of blood, turned into a suffocating blanket of pure dread.
It wasn't just fear. It was a biological imperative to submit. The mana density radiating from the boy was so absolute that it felt like the gravity had increased tenfold. Fen's glasses had slipped from his face, but he didn't move to catch them. Sable, the ever-vigilant rogue, was pressed flat against the stone, her forehead touching the dirt, her body refusing to obey her. Wick was catatonic, his eyes wide and unseeing.
They couldn't look up. They couldn't meet his eyes. To look at him was to acknowledge a predator that existed several steps higher on the food chain.
But Haruki stood.
His legs trembled. His vision swam. The pressure on his shoulders was immense, like carrying the weight of the dungeon itself. But he stood. The SSS+ fire in his left hand pulsed, not in aggression, but in defense, heating his blood, keeping him conscious against the crushing aura.
The boy noticed.
He tilted his head, the motion smooth, almost reptilian. The sheer terror he radiated seemed to part around Haruki like water around a stone.
"You," the boy said. His voice was soft, devoid of inflection, yet it cut through the silence like a blade. "You are interesting. You are afraid—I can smell it rolling off you in waves. Yet, you do not kneel. You do not break."
He took a step closer, ignoring the puddles of Cas's blood.
"Intriguing," the boy murmured. "I suppose courtesy dictates I should offer a name to the one who stands. I am Rico Ruban."
The name hit the group like a physical blow.
Maren, who had been frozen in a state of semi-shock, gasped. Her eyes dilated, the terror sharpening into a specific, horrific recognition.
*Ruban.*
The Ruban Lineage.
The history books in the Dominion didn't speak of the Rubans as mere demons. They spoke of them as Calamities. The Great Demons. Beings that predated the current era by millennia. Ancient, primordial entities that viewed the world as their garden and humans as weeds.
The Great Demons had been thought extinct, wiped out in the wars of the previous age. Their lesser descendants, the Demon Lords, had risen to power, only to be systematically hunted down and eradicated by the Heroes of the last decade. The world thought the age of monsters was over, that only the scattered, weaker demons remained.
But Rico was not a remnant. He was the source.
He was a Great Demon. A living fossil of extinction.
The realization shattered Maren's paralysis. She saw Haruki standing there, staring death in the face, and the instinct of a leader—the desperate, hopeless need to protect her team—overrode the terror.
She forced air into her crushed lungs.
"HARUKI!" she screamed, her voice cracking, raw and desperate. "RUN! JUST RUN!"
It was the last command she would ever give.
She collapsed forward, her strength giving out, her face hitting the cold stone.
Rico sighed. It was a bored sound. The sound of someone swatting at a fly that wouldn't stay down.
He flicked his wrist.
Thin, white strings shot out from his fingertips—different from the blades he had used on Cas. These were razor wires, invisible in the dim light, wrapping around Maren's unconscious form.
He lifted her into the air with a casual tug. Her body dangled limply, head lolling back.
"Why are you still talking?" Rico asked, his tone genuinely curious. "You don't see us talking. We are above conversation with livestock."
He tightened his fist.
The wires constricted. They weren't just holding her; they were digging in, sharpening, preparing to slice her into segments just like Cas.
"We value silence," Rico said. "So I will make you quiet. Permanently."
The wires began to bite into Maren's armor.
Haruki moved.
He didn't think. He didn't calculate. If he had thought, he would have realized the impossibility of the task. He would have realized that he was a Porter without a system, facing a Great Demon.
But he wasn't just a Porter. He was a vessel for a Primordial fire, and right now, that fire was screaming.
His left hand—the hand that held the shattered SSS+ stone—flared.
He didn't have a weapon that could cut the strings. But he had heat.
He reached into his pocket and grabbed the handful of Power Stones he had salvaged from the floor. Low-grade, unstable, and brimming with raw mana.
He clutched them in his palm.
*Rub.*
He rubbed the stones together violently, creating friction, while simultaneously unlocking the tiniest fraction of the *Cataclysm Touch* stored in his hand.
*Cataclysm Touch: Ignition.*
The stones didn't just spark. They detonated.
A concentrated blast of superheated fire—white-hot and blinding—erupted from his closed fist. It wasn't a spell. It was a chemical reaction of pure mana.
He thrust his hand toward the wires holding Maren.
The fire hit the strings.
For the first time, Rico's expression changed. It was a flicker of surprise.
The white wires, harder than steel and colder than ice, glowed red. They hissed, the mana in them destabilizing under the intense, chaotic heat of the Legendary stone's residue.
The wires snapped.
Maren dropped.
Haruki didn't hesitate. He lunged forward, catching Maren before she hit the ground. The impact jarred his bones, but he held on.
"MOVE!" Haruki roared, his voice sounding foreign to his own ears—deep, commanding, fueled by the fire in his chest.
He grabbed Wick by the collar of his shirt and hauled him up. He shoved Sable toward the dark tunnel exit. He dragged Fen by the arm.
He didn't look back to see if Rico was attacking. He just ran.
He pushed his body past its limits. He moved faster than he had ever moved in his life. He was a blur of motion, dragging and shoving his teammates into the narrow, winding side-tunnel that led deeper into the dungeon's bowels—away from the breach, away from Cas, away from the monster.
He moved so fast that even the air currents seemed to lag behind him.
Rico stood alone in the cavern.
He watched the white fire fade from the air where the wires had been. He looked at his fingers, which were slightly singed—the first injury he had sustained in decades.
He looked at the empty tunnel where Haruki had vanished.
The boy blinked.
Then, slowly, a smile spread across his face. It was a genuine smile, devoid of sanity, filled with a terrifying, childlike delight.
"You burned my strings," he whispered to the empty air.
He turned toward the tunnel Haruki had fled into. He didn't run. He didn't chase.
He just watched the darkness.
"Okay," Rico Ruban said, his voice echoing through the stone halls, soft and amused. "Let's play that game."
